This breaks resource allocation on alpha and probably other
arches with multiple pci domains. You cannot assume that resource
start is equal to the bus address of the respective BAR.
Even 32-bit BARs can have a resource->start well above 4G.
Yes, that will break some arches. The `max' should be calculated by
pcibios_bus_to_resource(). I'll fix this.
Thanks,
Yu
